Analysis of Thermophilic Microorganisms in Canned Bird’s Nest Production

Abstract:

A combination of 16S rRNA high-throughput sequencing technology and traditional culture methods was used to analyze and compare the microbial communities in raw materials for canned bird's nest and different production processes. Meanwhile, α and β microbial diversity analyses were used to investigate key control points for microbial contamination sources and processes in the canned production lines. The results revealed that the primary source of contamination in canned bird's nest production was the raw material of rock sugar, and the Geobacillus and Bacillus were the main contaminant genus responsible for the spoilage of canned bird's nest. Furthermore, the production processes associated with rock sugar raw materials in the production line were identified as the production critical control points. This study provides a theoretical basis for the production quality control and hygiene supervision in canned bird's nest production.
